Out of all the sports known to man, from tennis to baseball, from soccer to football, that I wouldn't never even consider even attempting to play because I know for a fact I would do horrible- swimming is the only sport that I enjoy and I actually do relatively decent at.
I hate heat, and the pool is the only thing that keeps me cool in the summer. Naturally I have to know how to swim. I'm nowhere near a professional, but I know enough to keep me above water. However, I do really enjoy it. It's one of the few things I look forward to in the summer. :D
